CVE-2026-6830

The CVE concerns nesquena Hermes WebUI, where switching profiles fails to clear environment variables from the previous profile, enabling leakage of sensitive credentials (e.g., provider API keys) between profiles. The underlying issue is residual environment variables that persist across profile...

CVE-2026-6830 Nesquena Hermes WebUI Environment Variable Credential Leakage via Profile Switch

nesquena hermes-webui contains an environment variable leakage vulnerability where profile switching does not clear environment variables from the previously active profile before loading the next profile. Attackers or users can exploit additive dotenv reload behavior to access provider API keys...

EUVD-2026-24131

XiangShan open-source high-performance RISC-V processor commit edb1dfaf7d290ae99724594507dc46c2c2125384 2024-11-28 has improper gating of its distributed CSR write-enable path, allowing illegal CSR write attempts to alter custom PMA Physical Memory Attribute CSR state. Though the RISC-V privilege...

OpenClaude: Sandbox Bypass via Early-Exit Logic Flaw Allows Path Traversal

A logic flaw exists in bashToolHasPermission inside src/tools/BashTool/bashPermissions.ts. When the sandbox auto-allow feature is active and no explicit deny rule is configured, the function returns an allow result immediately — before the path constraint filter checkPathConstraints is ever...

CVE-2026-29646

In OpenXiangShan NEMU prior to 55295c4, when running with RVH Hypervisor extension enabled, a VS-mode guest write to the supervisor interrupt-enable CSR sie may be handled incorrectly and can influence machine-level interrupt enable state mie. This breaks privilege/virtualization isolation and ca...

CVE-2026-29648

In OpenXiangShan NEMU, when Smstateen is enabled, clearing mstateen0.ENVCFG does not correctly restrict access to henvcfg and senvcfg. As a result, less-privileged code may read or write these CSRs without the required exception, potentially bypassing intended state-enable based isolation control...
